Thanks for this suggestion. It is indeed a useful idea, but difficult to combine with the remainder of the technology on our site. We rely on automatic transcription of the chords from youtube or other audio, but it is not yet possible to automatically transcribe lyrics. If we want to show lyrics, we should get them from some other source. Hence, I do not think we will support lyrics in the near future. However, youtube features a lot of songs with lyrics. If you chordify these you have your synchronised lyrcis on the side.

-Update-
We are actively looking into ways of incorporating lyrics to our player. More info on this soon!

Unfortunately we are still working out the legalities around displaying lyrics on our website, as lyrics are copyrighted content. We hope to eventually be able to offer lyrics to our users, but it’s unclear when this will be, sorry!

We agree, the bass note (or chord inversion as it is also sometimes called) is very useful information. After some investigation, it appears this would be a very large undertaking. We have however been working on this and we hope to implement this soon. Stay tuned!

You can't show left hand under notes for right hand? If you sent me the sheet music, I could do it. This isn't that difficult. As it is, the piano for Kate McKinnon's Hallelujah is not even close to the original.
